Email encryption protects messages in transit (TLS between servers, enforced by MTA-STS or DANE) and at rest or end to end (S/MIME, PGP, or portal-based encryption).
Is Gmail encrypted?
Gmail uses TLS in transit and encryption at rest. End-to-end encryption requires S/MIME (Workspace Enterprise) or client-side encryption.
Why does email encryption matter for deliverability?
Regulated data (health, financial, personal) requires protection in transit at minimum, and increasingly proof of it.
What is the first step to get started with email encryption?
Enforce TLS 1.2+ on inbound and outbound connections.
What is the most common email encryption mistake?
Assuming 'encrypted' in Gmail means end to end; it usually means TLS in transit.
